To get detailed information about an account use this the command account/get_account_data signature:

svc=account/get_account_data&params={"itemId":<long>,
                                     "type":<uint>}

or the 2nd signature for some accounts:

svc=account/get_account_data&params={"itemId":[<long>],
                                     "type":<uint>}
